SPECIFICATION forming part of Letters Patent No. 302,155, dated July 15, 1884. Application filed April 18, 1884. (No model.)

To all whom itmay concern:

Be it known that we, JOHN A. MULROONEY and \VILLIAM J. BRowN, of Rochester, in the consists in parts and devices, hereinafter fully described, and more particularly pointed out in the claim. A

Referring to the drawings, Figure 1 is a side elevation of a shoe last having a portion broken away andparts centrally sectioned as on the dotted line 00 in' Fig. 3, to show more fully the invention; Fig. 2, an elevation of the opposite side of' the last, the latter'being inverted, or in the position occupied during the process of lasting, parts being sectioned and brokenaway to show the locking-bolt in position to hold the block; and Fig. 3, a plan of the last, viewed as indicated by arrow in Fig. 1.

Referring to the parts, A is a last of common form, consisting of a main part or body, 0, the usual removable block or piece, B, fitted thereto, forming the instep of the last. The

blockB is fitted at the thin end I) to the body of the last with the usual V point or angle, a, to prevent said block from sliding 0r swinging laterally on its seat or bearing against the last during the process of lasting shoes. When the cloth or leather is drawn tightly across the last along, the part indicated by the broken line a 0, there is a great tendency to draw the block B ba'ck or in a direction away from the toe of the last to the position shown in Fig. 3, which causes the shoe to be formed too'small across the instep, seriously to the injury of the fit of the same. In'pra ctice, nails are frequently driven temporarily through its rear thin edge, 1;, of the block into the last, as indicated by the dotted line 6, to hold saidblock to place handling.

To supply a permanent automatic lock ,or fastener for the block, consisting'of an adjustable piece to reach across the joint h, between said last and block, in lieu of nails or other objectionable devices, and so hold the block from sliding, is what we aim to accomplish in our invention. We prefer the sliding pin or bolt shown at a, resting in bothpieces 0 and B, for this purpose, though any other device having a bearing in or against both parts simultaneously would answer the purpose;

In using the pin a, opposing cavities d and g are formed in the last and block, respectively, having a common axis crossing the joint h between them at about right'angles. Short metallic tubes 0. and 0 are snugly inserted in the respective cavities, so that their outer ends shall bej ust even with the surfaces of the last and block at the joint h. vided with a head, 8, within the last, the tube 0 being shorter than the depth of the hole d, so as to allow-space for the head of the pin to move in. it .fills without binding thebore of the tubes. Thus constructed, the pin is a-permanent fixture of the last, but it may move longitudinally, so as to have its point project beyond the surface at the joint .h, so as to enter the tube 0, as shown in Fig. 2. The pin is designed to move within the tubes wholly by gravity,

and when dropped to the bottom of the hole d to be wholly within the last, having its point about even with the joint 71. between the parts of the last. when the last rests upon its sole,

as shown in Fig. 1, the pin drops wholly within the part 0, out of the way; but when inverted for the purpose of performing the op- .The pin a is pro- 7 1 The diameter of the pin is such that tion on its bearing, with the last. .The pin n I is placed in the opening d, head downward, before the tube 0 is inserted, and the head of the pin when thus placed in the last forms a means to prevent the pin from dropping out of the last and getting lost, at any time, from The tubes 0 0 may be made of hard rubber or other suitable material instead of metal, if automatically, so as to rest with a portion of desirable, the object being, in part; to line the its length in each of said parts of the last, when holes in the wood to prevent wear.
